The S N 1 reaction energy diagram illustrates the dominant part of the substrate with respect to the reaction rate. The rate-determining step is the formation of the intermediate carbocation, or carbenium ion. Energy Diagram For Sn2. It starts with the kinetics of SN2 reaction and covers the energy diagrams including questions on activation energy, enthalpy, the order of reaction and curved. SN2 Reaction follows second order rate kinetics. It forms a product via one transition state. Transition state is the state at which it posses.

Figure 7.3 shows an energy diagram tracing the progress of a reaction that occurs by an S N 1 mechanism. The rate of the reaction reflects the activation energy required to form the carbocation intermediate. The activation energy required for step 2, addition of the nucleophile to the carbocation, is much smaller, so step 2 is very fast.

Identify The Correct Potential Energy Diagram For A S

I just need some clarification for drawing this energy diagram. I'm drawing the diagram for an SN1 reaction, and for this reaction there is a hydride shift to make the carbocation more stable. Anyways, I know that on the diagram there exists at least one valley because there is at least one intermediate. I'm not sure if I'm supposed to draw another valley, because of that shift orrrr does one valley represent the carbocation before AND after the hydride shift?
